我厂一批深孔零件(油缸体),材料30CrMnSi,调质硬度HRC33～38,孔径φ100D_3,孔长565毫米,盲孔,内孔光洁度▽9,因无深孔磨削设备,便利用一台普通外圆磨床M115W,改制成一台深孔磨床。经磨削试用,性能良好,磨削光洁度达▽8～▽9,工作稳定,已投入批生产使用。结构如图示。改制方法和步骤如下: 1.根据被加工零件孔的长度1,和外圆磨床工作台纵向最大行程L(L>1),选择 I plant a group of deep hole parts (cylinder body), material 30CrMnSi, quenching hardness HRC33 ~ 38, aperture φ100D_3, hole length 565 mm, blind hole, inner hole finish ▽ 9, because no deep hole grinding equipment, Taiwan ordinary cylindrical grinder M115W, transformed into a deep-hole grinder. After grinding trial, good performance, grinding finish up ▽ 8 ~ ▽ 9, stable, has been put into batch use. Structure as shown. The method and steps are as follows: 1. According to the length of the machined part hole 1 and the longitudinal maximum stroke L (L> 1) of the table of the cylindrical grinding machine, select
